Where Areva's grants concentrate

Areva Stockage D'energie is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2019. By volume, Areva sits between Aquahydrex PTY Ltd and ARK Crystal, Llc.

Areva's three-year grant acceleration

Areva Stockage D'energie shows 2 grants in 2022–2024 against only 3 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
